### My students' writing

A friend and colleague of mine, Prof. Andrew West, gave me the idea of having my students maintain research blogs, both as a way for him to keep up with what they are doing and for the student to practice writing.

This has worked so well for my mentees that I decided to use it in my Intro Astro course. I was further encouraged by this article, in which the author Prof. Cathy Davidson notes
Given that I was teaching a class based on learning and the Internet, having my students blog was a no-brainer. I supplemented that with more traditionally structured academic writing, a term paper. When I had both samples in front of me, I discovered something curious. Their writing online, at least in their blogs, was incomparably better than in the traditional papers. In fact, given all the tripe one hears from pundits about how the Internet dumbs our kids down, I was shocked that elegant bloggers often turned out to be the clunkiest and most pretentious of research-paper writers. Term papers rolled in that were shot through with jargon, stilted diction, poor word choice, rambling thoughts, and even pretentious grammatical errors (such as the ungrammatical but proper-sounding use of "I" instead of "me" as an object of a preposition).
But it got me thinking: What if bad writing is a product of the form of writing required in college—the term paper—and not necessarily intrinsic to a student's natural writing style or thought process? I hadn't thought of that until I read my students' lengthy, weekly blogs and saw the difference in quality. If students are trying to figure out what kind of writing we want in order to get a good grade, communication is secondary. What if "research paper" is a category that invites, even requires, linguistic and syntactic gobbledygook?
I've already found this to be true. Remarkably true, in fact. Check out the first handful of blog posts from my students. I was anticipating that I'd have to give a lot of feedback and corrections on their initial posts, but they all came out of the starting blocks blogging like pros!

Daniel Lo: The Night Beckons
David Vartanyan: Abstrosizics
John Pharo: Looking Up
Juliette Becker: Starstruck
Lauren Gilbert: Ay20
Mee Wong-u-railertkun: CQ, this is W9GFO.
Monica He: Ay20
Tommy Heavey: A Chemist in Astronomy

Please leave comments if you really enjoy any of these posts. They need all the encouragement and feedback they can get on their way to becoming professional scientific researchers.

Awesome!

I wonder why it's so much easier for some people to communicate this way. I know I was pretty awful at technical writing, but I always did well on the creative side of things. Could it be it's just a mindset thing, where they think they're being creative and doing something as simple as blogging, which makes it easier, instead of formally typing up a paper?

### On the Height of J.J. Barea

Dallas Mavericks point guard J.J. Barea standing between two very tall people (from: Picassa user photoasisphoto).

Congrats to the Dallas Mavericks, who beat the Miami Heat tonight in game six to win the NBA championship.

Okay, with that out of the way, just how tall is the busy-footed Maverick point guard J.J. Barea? He's listed as 6-foot on NBA.com, but no one, not even the sports casters, believes that he can possibly be that tall. He looks like a super-fast Hobbit out there. But could that just be relative scaling, with him standing next to a bunch of extremely tall people? People on Yahoo! Answers think so---I know because I've been Google searching "J.J. Barea Height" for the past 15 minutes.

So I decided to find a photo and settle the issue once and for all.

I then used the basketball as my metric. Wikipedia states that an NBA basketball is 29.5 inches in circumfe…

### Finding Blissful Clarity by Tuning Out

It's been a minute since I've posted here. My last post was back in April, so it has actually been something like 193,000 minutes, but I like how the kids say "it's been a minute," so I'll stick with that.
As I've said before, I use this space to work out the truths in my life. Writing is a valuable way of taking the non-linear jumble of thoughts in my head and linearizing them by putting them down on the page. In short, writing helps me figure things out. However, logical thinking is not the only way of knowing the world. Another way is to recognize, listen to, and trust one's emotions. Yes, emotions are important for figuring things out.
Back in April, when I last posted here, my emotions were largely characterized by fear, sadness, anger, frustration, confusion and despair. I say largely, because this is what I was feeling on large scales; the world outside of my immediate influence. On smaller scales, where my wife, children and friends reside, I…

### The Force is strong with this one...

Last night we were reviewing multiplication tables with Owen. The family fired off doublets of numbers and Owen confidently multiplied away. In the middle of the review Owen stopped and said, "I noticed something. 2 times 2 is 4. If you subtract 1 it's 3. That's equal to taking 2 and adding 1, and then taking 2 and subtracting 1, and multiplying. So 1 times 3 is 2 times 2 minus 1."

I have to admit, that I didn't quite get it at first. I asked him to repeat with another number and he did with six: "6 times 6 is 36. 36 minus 1 is 35. That's the same as 6-1 times 6+1, which is 35."

Ummmmm....wait. Huh? Lemme see...oh. OH! WOW! Owen figured out

x^2 - 1 = (x - 1) (x +1)

So $6 \times 8 = 7 \times 7 - 1 = (7-1) (7+1) = 48$. That's actually pretty handy!

You can see it in the image above. Look at the elements perpendicular to the diagonal. There's 48 bracketing 49, 35 bracketing 36, etc... After a bit more thought we…
